Standard plugs, even those used with sealing compounds and washers, are prone to spiral leaks. MAGNASEAL® Self-Sealing Plugs have two annular sealing rings that maintain a liquid tight seal even after repeated installation and removal. MAGNASEAL® Self-Sealing Threaded Plugs have proven so effective that they eliminate the need for separate sealing washers or sealing compounds, and the dual sealing rings allow multiple removals and reinsertion, up to 10x.
